In my opinion, it is as difficult to believe in nothing as it is to believe in something. It mostly depends
on what the something is. Now, the belief in a Supreme Being automatically includes a world view.
A lot of what that world view is, is about relationships. Simply, it is this, if there is the possibility of
continuous progress, then that creates a great sense of " freedom "..... ( what ever that means ? ),
and then it somehow includes a basis for the idea of love.
Bottom line, there's a lot in the package.
However, as with most things, when you get a big package there are bond to be difficulties
as well. In particular, with a Supreme Being you also get a kind of requirement for belief,
because with few exceptions - no body really can get the details, like what kind of
candy the Supreme Being likes, or if He really has an English accent - things like that.
I bet a lot of people in France suspect He speaks French. Maybe, not sure.
